The Norwegian Grade is a 2 miles (3.2 km) section of Moorpark Road from the Santa Rosa Valley up into the Simi Hills and the city of Thousand Oaks, within Ventura County, California.
[2] After several mishaps while hauling crops down the Potrero- and Conejo Grades, men of the Norwegian Colony decided to construct a new route.
[4] The road was carved out of a steep canyon hillside by members of the Norwegian Colony in Thousand Oaks, and their hired help, between 1900 and 1911.
[5] These settlers, known as the Norwegian Colony, needed a safe way to move bales of hay and sacks of wheat and barley to the Oxnard Plain and the Hueneme Wharf.
[8] The campus was donated by the Pederson family, who were among many Scandinavian immigrants populating the hills of northern section of the Conejo Valley.
The resulting rocks and debris were moved by hand and a horse-drawn fresno scraper to build the narrow, one-lane roadway.
